Question

a, b, c are zeroes of cubic polynomial x3 - 2x2 +qx -r.If a + b = 0 then show that 2q = r.

Answer 1

Answer:

ax bx c. = +. + where a, b, c, ∈R and a 0. ≠ is called a quadratic polynomial. 'a' is called the leading ... x + (q + r – 2p)x + (r + p – 2q) = 0 has a root in (-1, 0) then find the nature of the roots of 2 px.
